IMPROVEMENT IN TINNERS AND PLUMBERS FURNACES.

Specification forming part of Letters Patent No. 2513914 dated May 26,1874; application filed April 29,1874.

To all whom it may concern:

Be it known that I, J oHN P. HAYES, of the city of Philadelphia, in theState of Pennsyl Vania, have invented an Improved Furnace for Tinnersand Plumbers7 Use, of which the following is a specification:

My improvement relates to the portable iron furnaces in which the heatis produced by the combustion of fluid hydrocarbons, supplied to burnerfrom a communicating fountain-head; and the object of my invention is toproduce a simple and economical portable furnace for the use of tinnersand plumbers for heating their solderingirons and melting solder forconnecting lead pipes.

Figure 1 is a vertical longitudinal central section of said furnace andthe regulating supply-cock in a section of the pipe leading to thefountain-head, (not shown 5) Fig. 2, a perspective view of theiiame-defector, detached; and Fig. 3, a perspective view of asupporting-frame to be substituted for the deflector when thesoldermelting pot (not shown) is applied over the vaporizer.

The body A of the furnace is circular, tapered downward from its opentop to a point a little below the hearth a', and then contracted so asto form a iiat circular shoulder a, which supports it upon the base B,into which the sunken chamber 3, closed at its bottom, enters andextends about halfway down into said base B, as shown in Fig. l. Thebase B is oblong, rounded at both its its ends, and has numerous` largeopenings around through its sides, as shown. The body of the furnace Arests at one end of the base B, and through the top ofthe opposite orprojecting end of said base a vertical pipe, c, coming from an elevatedfountainhead, (not shown,) connects with the stop and regulating cockc', which is supported on the base B, and connects with the horizontalpipe D, which extends horizontally along in the said base, enters anappropriate hole in the side of the combustion-chamber 3, and thenextends vertically upward a short distance, and in an arched form, justbeneath the horizontal plane of the hearth, nearly to the opposite sideof the chamber 3, thence downward, and finally upward to within a shortdistance below the arch d', where it ends in a small jet-hole, d,directly beneath said arch. The horizontal portion of the pipe D ispacked with plaster-of-paris, or other non-conductor of heat, and aslender hole made through its center from 4 to 5, through which the Huidhydrocarbon passes before it reaches the combustion-chamber 3, and isthus prevented from becoming heated therein. The uid becomes heated andvaporized in passing through the arched portion d', and is discharged soas to burn from the jet d, whereby the fiame is directed upward againstand around the vaporizer d. The removable deector E is a curved plate ofcastiron, which extends from the mouth of the furnace horizontallybackward to the opposite side of the same, leaving open spaces betweenits two side edges an d the respective opposite sides of the furnace,and is supported by legs c and a downward-projecting part, e, of itsrear end, both of which rest upon a shoulder, 5, in the inner side ofthe furnace, so that the arched plate of said dcflector will be abouttwo or two and a half inches above the arched vaporizer d', or at such adistance above the vaporizer d', or the horizontal plane of the heartha', as will just allow of the usual soldering-irons (not shown) beingintroduced with facility from the hearth, the latter afterwardsupporting the handle ends thereof, and the cross-bar 6 support ingtheir points while subject to the heating-flame, the said cross-bar 6being supported transversely and horizontally across the furnace in thesame plane with the hearth a.

"When the plumber desires to melt his pot of solder, he removes thedeflcctor E and inserts in its place the skeleton supportingframe shownin Fig. 3, with its throat 7 iitting closely around the opening from thehearth a', and its bottom rim S around against the sides of the furnace,so as to compel the draft from the hearth-opening to pass down under therims 7 and S of the skeleton support, :md thence up against the bottompurpose of directing the draft and heat of a melting-pot, which may bethereon, mainly to the bottom of a melting-pot supzmd thus concentratingthe heet at said botported thereby.
